52151240 ÷ 43 
We're looking to find how many times 43 goes into 52151240.

Going ahead to step 1:
43 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 43

Moving on to step 2:
43 can be fit into 52 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 43 from 52 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 43

Going ahead to step 3:
If we divide 91 by 43, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 86 from 91 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 43

Moving on to step 4:
If we divide 55 by 43, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 121.0
The remainder is 12 after subtracting 43 from 55.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 43

Let's proceed to step 5:
The number 43 fits into 121 2 times, leaving a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 1212.0
Subtracting 86 from 121 leaves us with 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 43

On to step 6:
When dividing 352 by 43, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 12128.0
Subtract 344 from 352 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 43

On to step 7:
If we divide 84 by 43, we get 1 and a remainder of 41.
The next digit of our result is 1. 
Result so far: 121281.0
Deduct 43 from 84 and we're left with 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 43

Advancing to step 8:
43 can be fit into 410 9 times, resulting in a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 1212819.0
If we subtract 387 from 410, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
The number 43 fits into 230 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 1212819.5
The remainder is 15 after subtracting 215 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
150 divided by 43 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 1212819.53
Subtract 129 from 150 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
The number 43 fits into 210 4 times, leaving a remainder of 38.
The next digit of our result is 4. 
Result so far: 1212819.534
The remainder is 38 after subtracting 172 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
When dividing 380 by 43, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 1212819.5348
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
If we divide 360 by 43, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1212819.53488
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 1212819.53488, and the remainder is 1.6e-05.
